"The first installment in Orson Scott Card's classic science-fiction series offers a gripping study of how to make a soldier, told through the eyes of child prodigy Andrew "Ender" Wiggin. Set at a futuristic school where kids learn the art of war through battle simulators, Ender's Game shows the vicious toll that thankless expectation exerts on young people, while Ender's own journey has an uneasy sort of "chosen one" edge to it. Card expertly twists your emotions as you watch the boy genius molded — not entirely with his own permission — into the perfect leader, with his capacity for love and hurt compartmentalized behind ruthless cunning. Ender's voice is a mesmerizing mix of childlike wonder and calculating cynicism, and it's stunningly easy to get lost in his war games. This exemplary piece of sci-fi is a chilling and heartbreaking take on what happens when children inherit war."
